The primary objective of the present trial is to investigate, the mean operative time and to study the frequency and intensity of postoperative shoulder tip pain in patients undergoing laparoscopic surgery, i.e. cholecystectomy, colorectal surgery, hernia repair with AirSeal® compared with standard pressure CO2 insufflation systems. The primary hypothesis is that patients operated with AirSeal® have a shorter mean operative time and decreased frequency and intensity of postoperative shoulder tip pain compared with patients undergoing surgery with standard pressure CO2 insufflation systems.
